Example program in C/C++
This program shows how to establish an SDLC V29FastPOS link and keep the loop alive.
How to use the program:
It is only meant to run a few minutes for testing.
The program is run after a reset is done and loads the patch it loads from "patch.txt" and calls using the atdt line it
finds in "tel_no.txt". Both files need to terminate in CR LF.
The tel_no.txt file must contain a complete telephone number dialing line followed by a CR, e.g.
ATDT8,5551212.
